To all whom t may concern: V

Be it known that I, BENJAMTN SWAGER, a citizen of the United States, residing at Saunemin, in the county of Livingston and State of Illinois,l have invented certain new and useful Improvements in Vaporizing Apparatus for Internal-Combustion Engines; and I do declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and use the same.

This invention relates tomeans for improvingthe operation of ipternal combustion engines.

The principal object of the invention is to provide means whereby kerosene or similar oil in combination with water may be fed to the cylinders of an internal combustion engine in vaporized form, the heat'necessary for causing this vaporization being supplied by the exhaust gases of the engine.

y A secondary object is to provide an im proved air control valvefor supplying varions quantities of air to the vaporized kero- `sone and water.

, With these\and other objects in view the of parts which will be hereinafter more particularly described and shown. in the accompanying drawings wherein 4 tomo Fi ure 1 is a perspective viewfof an aul(bile engine having my improved apparatus applied thereto ;l

Fig. 2 is a horizontal section through the exhaust manifold of the engine shown in Fig. 1, illustrating more particularly the application of certain parts of my invention; Fig. 3 is a longitudinal sectional view of the improved automatic air valve used yin connection with the other parts of the apparatus; and

Fig. 4 is a similar view of the control valve. y z

The invention may be applied to practically any type of internal combustion en gine, but preferably one having its intake and exhaust manifoldson thesame side as shown in the accompanyingdrawings. In these. drawings a conventional form of hydro-carbon or internal combustion engine E is illustrated, the same having an intake manifold 1,; an exhaust manifold X and a water manifold W, the latter' `being connected to the usual radiator A carburetor supplies fuel in vaporized form to the intake manifold, the liquid from which this f gas`is formed preferably heilig gasolene.

e cylinders of the dinarily only one of these liquids is used at one time, but by the structure -which is shown in the accompanying drawings both may be simultaneouslyA supplied in the form vof vapor. y

In carrying out my invention a rather long vaporizing pipe 1 is disposed within the exhaust manifoldXlongitudinally there of, said pipe entering at one end through an opening 2 and extending nearly to the opposite end. The end of the pipe l which projects through this opening 2 is the inlet end and is connected by .a suitable connection such as the union 3 to a supply pipe 4c, the latter being extended' upwardly and connected to a tank 5 of any preferred size. This tank is' mounted above the engine by any desired means so that the kerosene or other similar oil which it containsmay be fed to the vaporizing pipe by means of gravity. l adjacent its connection with the union 3, this valve being designed to control the flow of liquid from the tank. The other end of the vaporizing pipe which terminates within the exhaust manifold has a' right angular outwardly extending portion 7` connected theretox,A such extension projecting through an opening in the wall of the manifold X. The novel form of automatic air cont-rol valve 8 is connected to this extension-` 7, its specific formation and operation will be hereinafter more particularly described.

In addition to kerosene, water is also fed to the vaporizing pipe 1, this water being supplied by the cooling system of the en- A valve 6 is positioned in the pipe 9 is extended downwardly andj oins the supply pipe 4 between the valve 6 and the union 3. Thus by regulating thevalves G and 1() any desired quantity of kerosene and water, may be allowed to 4run into the inlet end of the vaporizing pipe, where the head generated by the explosions within the cylinders of the engine will cause this mixture to become vaporized andthoroughly mixed, the

water being turned into steam and super-V heated before it reaches tt end of the va'- porizing pipe, and the kerisene turned into a gas. 2

This mixture and the liquids from which it is formed are drawn into and through the vaporizing pipe 1 by the suction in the-cylinders of the engine in the saine manner as the charges of explosive mixture are drawn from the carbureter C. After enteringithe aircontrol valve 8 which is at the outletend of the vaporizing pipe, the mixture of steam and gas is carried through a connecting pipe 11 vwhich joins the last mentioned valve with 'the control valve 12, the operation of which' is regulated by the operator of the lvehicle from any suitable point within the body of the machine. By adjusting this last mentioned valve the supply of steam and gas into the intake manifold l. is limited.v A short pipe 13 connects the valve 12 with the intake manifold above the carbureter C.

The automatic air control valve 8 consists of a vcylindrical casing 14 which. is open at one end and internally screw threaded, the

clos-edv end being centrally apertured to receive the apertured end of the extension 7. The side walll of the casing let is also apertured for the reception of the end of the connecting pipe 11. A plug 15 is secured into the threaded end of the casing said plug having a boss 16 whereby the same maybe easily rotated. This plug and the boss formed integrally therewith is centrallyl apertured to :receive a tubular valve stem 17 which is slidably disposed therein, said stem having a head 18 positioned within the casing 14 and adapted to bear against the .inner face of the plug to normally close'a pair of inlet openings 19 formed therethrough, one on each side of the eentral opening. An' expansion coiled spring 20 engages the. valve head and the closed end of .the easing to normally keep said valve in operative position, said spring being maintained centrally within the casing by the inwardly .extending end 21 ofthe expansion pipe 7. The passageway 17 Within the valve-stem 17 is of-r relatively small diameterso that very little air may enter the valve casing except? through the passage-ways 19, the latter being closed except when there is excessive suction within the enginecylinders.'

From this descri tion taken in connection with' Fig. 3 it ywill be seeiivthat a small y quantity of air isl being continuously drawn into, the stem and 4mixed with the gas formed from the kerosene and the Steam when the latter passes through the. valve easing 14 from the extension pipe 7 to the connecting pipe' l1, the diameter of the lat-y ter being relatively large compared withv will act asa vent-*to permit the excess gases f toiescape without damaging any of the parts vof' the apparatus.

Under ordinary operation of the invention this passageway will 'the size of the inlet passage 17 ,In 'case operate only as an -air inlet and'not asa vent.

As above mentioned, the supply of'vapor .i

from the vaporizing pipe to the intake manifold is regulated bythe Vval-ve 12, the same being ,formed of. a tubular casing 22 and having one open end internally threaded to receive the externally threaded plug 23.' The saidplug has a central opening 2i through which extends a' valve stem 25, the

outer end being connected by suitable con trol levers (not shown) to a foot operated. device within the body 'of the vehicle; the

other end of the valve stem has a'head 26 which cooperates with a seat 27 formed in the end of the connecting pipe 11 which ex* tends through an opening in the closed end of said casing. A- coiled spring 28 surrounding the va'lve stem 25 'i between the head 26 thereof and the plug 23 normally retains the valve closed.v In both of the valves 8 and 12it will be obvious that by adjusting their respective plugs inwardly, the tensionof the springs therein will be Vvaried so that the operation will be vmore or less diflieult. l

Various changes may be made in the form and proportion of this improved vaporizing apparatus to accommodate the same to use on various forms and types of internal com.-

bustion engines including both thosek used on automobiles and other vehicles and those ordinarily known as stationary engines.
